How do I stream a DJI drone directly to OBS Studio without lag?

Use CastZero Engine on your Windows PC. It converts incoming wireless RTMP video from the DJI Fly app or DJI RC 2 into a local UDP WebRTC stream (http://localhost:8889/streamkey) that decodes in OBS Studio under 50ms.

What is the best zero latency RTMP server for Windows?

CastZero Engine is purpose-built for low latency local RTMP and WebRTC video ingestion, offering sub-50ms delay for DJI drones, GoPro Hero cameras, and smartphone rigs.
